Unvip doesn't trigger chat moderators actions pubsub topic reliably
This should be cross checked to ensure the workflows trigger the expected/correct things across other parts of Twitch.
I'd of expected that unvip is a moderator action to be broadcasted to the pubsub topic where I'm subbed as the broadcaster so that unvip can be monitored.
But if it's not supposed to then thats fine.
I'm sure it's intermitten though, will check around my logs further
Add mod/vip will send a pubsub topic to the target, all the mods, as well as the channel. Remove mod/vip will only send a pubsub topic to the target user. Is this the behavior you were seeing?
